Bug#779175: error 403 for https

[Harald Dunkel <harald.dunkel@aixigo.de>]

Package: apt-transport-https
Version: 1.0.9.6

My /etc/apt/apt.conf.d/proxy.conf says

	Acquire::http::Proxy "http://debian-proxy:3142/";;

debian-proxy is a local host running apt-cacher-ng.

Problem: On apt-get update I get

	Err https://get.docker.com docker/main amd64 Packages
	  Received HTTP code 403 from proxy after CONNECT

If I drop the proxy redirection, then it works.

Since there is no "https" in the Acquire line, shouldn't the
proxy be omitted for https traffic automagically?
